    afety Notes

    2 Safety NotesThe following safety notes apply to the use of motors.

    If using gearmotors, also refer to the safety notes for gear units in the correspondingoperating instructions.

    Also take account of the supplementary safety notes in the individual sections ofthese operating instructions.

    Explosive gas mixtures or dust concentrations in combination with hot, energizedand moving parts of electrical machinery can cause serious injury or death.

    Mounting, connection, startup, maintenance and repair must only be performedby trained personnel observing

    these instructions

    the warning and information signs on the motor/gearmotor,

    all other project planning documents, operating instructions and wiring diagrams

    system-specific regulations and requirements

    currently valid national/regional regulations (explosion protection / safety / preventionof accidents).

    Intended usage These motors/gearmotors are intended for industrial systems1. They correspond to theapplicable standards and regulations:

    EN50014

    EN50018 for protection type "d"

    EN50019 for protection type "e"

    EN50021 for protection type "n"

    EN50281-1-1 for "dust explosion protection"

    They also comply with the requirements of directive 94/9/EC.

    The technical data and the information about permitted conditions are to be found on thenameplate and in these operating instructions.

    It is essential to observe all specified information!

    Transport / storage

    Inspect the delivery for any damage in transit as soon as you receive the delivery.Inform the transport company immediately in the case of damage. It may benecessary to preclude startup.

    Tighten screwed in transport lugs firmly. They are only designed for the weight of thegearmotor/gear unit; do not attach any additional loads.

    The installed lifting eyebolts comply with DIN 580. The loads and regulationsspecified in this standard must always be observed. If the gearmotor is equippedwith two suspension eye lugs or lifting eyebolts, then both suspension eye lugsshould be used for transport. In this case, the tension force vector of the slingsmust not exceed a 45 angle in accordance with DIN 580.

    Use suitable, sufficiently rated handling equipment if necessary. Remove any transportfixtures before startup.

    1 and may only be used in accordance with the information provided in SEW-EURODRIVEs technical do-cumentation and the information on the nameplate.
